Abstract

Texas Instruments has developed a phase light modulator (PLM) based on Micro-Electromechanical System (MEMS). This modulator offers several excellent advantages, including high refresh rate, compact optical path, and high optical efficiency, making it well-suited for applications in laser displays. In this paper, we divide the PLM into three regions and illuminate them with corresponding color laser light. The diffracted image is eventually reproduced and superimposed at the image plane in order to obtain a colorful display. We measured the display indicators such as inherent resolution, coincidence error, contrast ratio, uniformity, optical efficiency and diffraction efficiency of this methodology. The advantages of this methodology lie in its compact optical path and excellent optical efficiency. This work enhances the development of single PLM for color laser display applications in field sequence, including holography and volume display.
